The Colosseum has 76 entries, but we did not enter even one. We admired it from the outside. The entrance was 12 euros and there was nothing going on inside. In Roman times, the entrance was free for everyone. Of course, the first level of the Colosseum was reserved for the emperor and his senators, so they could watch bloody gladiators fight from the closest distance. The Colosseum is not just about ruins though, it is also a vibrant place where people can enjoy opera or rock concerts too.
